I am having trouble with ButterKnife. I found that butterknife doesn't use inject anymore so I refactored my code to use @Bind but still cannot seem to find where the issue is. I want to butterknifes github and dug through the docs and tried to find if I was missing something but still nothing.

When you created the MainActivity did you use the Blank Activity (which is anything but blank these days) or Empty Activity? Blank splits the layout into two files with second <include>-ed in the first and ButterKnife has an issue with that. https://github.com/JakeWharton/butterknife/issues/393

I think I found the problem.

In my updateDisplay() I forgot to include the empty string to convert the value returned from getPercipChance(). Changed the line to mSummaryLabel.setText(mCurrentWeather.getPercipChance()+""); and it seems to be working now. I am not sure why I can't see the errors like the video shows or else I could have found this a lot easier. The only error I get is the one I pasted above. I tried looking around in the different panes but can't seem to find it.

This is really fun stuff and I feel like I understand it but have no clue where to start on my own project. This is probably typical learning java, at least I hope so. :) Thanks for your help.

Well I think I was wrong above, I do have two layouts, and when I copied one and pasted into the other that must have fixed it. I didn't figure it out until I went on to the next lesson and changed something in the view and it happened again. Can I delete one of the views or how do you stop this from happening? Why did it happen?
